To all whom it may concern:

-Be it known that 1,;GE0RGE J. ABER- NATHY, a citizen of the United States, residing at `Ambrose, in'the'county of Grayson and State of TeXas','have invented Vnew and useful Improvements in Jacks, of which the following is a specification.

This invention relates to jacks, especially adapted for use upon motor cars and similar vehicles, and hasfor itsgprimary lobject to providea jackof this character, which may be folded into a compact condition, for storage, within the tool chest of the machine. i A :further object of the invention lis to provide a device of this character, in which the unfolding of the jack .will cause the same to assume its normal working position, andv also moves the operating lever forthe jack to its normal or starting position withinl convenient reach of the `operator ofthe jack.

A further object of the invention is to provide a" jack' ofthe character -described'in which the slide block to which the load iin-' posed upon the jack is attached is drawn to its normal or lower-most position by the folding of the jack.

A further object of the invention is to provide a device of the character described which is simple in construction, cheap to manufacture and highly ethcient in use.

The invention consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

The preferred embodiment of the invention has been illustrated in the accompanying drawing, but no restriction is necessarily made t0 the precise details of construction therein shown, as changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawings :-Figure 1 is a perspective view of the invention applied to the rear axle of a motor vehicle and in the initial position for raising the same. Fig. 2 is a side elevation of the invention showing a portion of the rear axle of the motor vehicle connected thereto and in a raised position. Fig. 3 is a longitudinal sectional view showing the jack detached from the axle of the motor vehicle and in a folded condition.

sponding parts throughout the several views. The numeral 1 `designates a portionof a motor vehicle and the rear axle connected therewith, the *said axle being connected as at 2 withthe jack constructed in accordance with the invention. i lThe jack proper comprises a pair of chanfneled sections 3 and 4. The sections 3'and 4 are united to provide a standard by means of a hinge joint, as at 5, and upon the pintle pin 6 `of said hinge joint is mounted an operating lever7 having a fork end 8. The

`fork end 8 of the lever 7 is provided adja- -cent its connection with` the pintle pin 6 withgperforated ears 9. 4The `upper channeledsection4 is slotted as at 10 upon oppositesidesthereof while the lower channeled section 3 is provided with a base portion 11 having-a spring.l clip'12 thereon for engage- `.ment with the standard 4 when the same is in a folded position. Mounted for sliding movement upon the upper channeled section 4 is a U-shaped load carrying block 13 secured to the section 4 by means of a pin 14 passing through the slots 10 in said section, and a plate 15 bolted upon the ears 16 'of the load carrier 13. rIhe ears 16 of the load carrier 13 are further provided With openings 17, said openings being adapted to receive the threaded ends of the U-shaped clips 18 which are passed around the axle 1 of the motor vehicle secured to the ears 15 by means of bolts 19, thereby securing the load carrying block to the weight to be lifted.

Eccentrically connected as at 19 to the ears 9 of the fork lever 7 is a link 20 having one end thereof secured by the pin 14 to i the load carrying block 13. r1`he load carrying block 13 is adapted to engage recesses 22 formed in the channeled sections 3 when the standard 4 is in a folded position.

From the foregoing description taken in connection with the accompanying drawing it is readily apparent that when the section 4 is moved to an upright position and the weight to be lifted connected with the load carrying block 13 and the fork lever 7 moved toa lowered position as shown in Fig. 2, an

effectual jack Will be provided. Further more it ywill be seen `through the link con;

nection with the lever 7 when said lever is in its lowered position and the Weight attached to the block 173, the back of the standard 3 being in engagement with the lever 7 sustains the Weight upon the block 13 in a raised position. It is also obvious that When the jack is unfolded the action of the link 20 upon the lever 7 forces the same -pintle, a load carrying block slidable upon .one of the sections, a forked lever mounted upon said pintle, and a link eccentrically connecting said lever With the load carrying block.

2. A jack comprising a channeled standard formed from sections hingedly connected together by means of a =pintle intermediate the ends of the standard, a load carrying block slidable upon and Within one of said standards, a forked lever mounted ideama upon the above mentioned pintle, and a link eccentrically pivotedtosaid leverand connected With the loadbarryns bleek-l f 3. A jack comprising channeled sections adapted, when united, to form a standard having a hinge joint intermediate the ends thereof, one of said sections being provided .with alined slots, a load carrying block slid- 'able upon one of the channeled sections and in said slots, means for connectingthe load to said block, a lever having a forked end fulcrumed upon thel standards, and a link the load carrying block. .Y
